Rework Procedure
Disconnect the IAP control valve connector (seeIllustration 1).
Cut the wires behind the connector.
Strip the ends of both wires.
Install 2324367 harness by crimping the strippedwires inside the splice. Take care to connect pink wire to pink wire onone hand, purple wire to purple wire on the other hand.
Heat both heat shrinkable tubes in order to insulateboth splices.
